Sophia exchanged 1,000 US dollars for the south African currency. the exchange rate was 7.15 rand to $1.00.

1 / 7.15 = 1000 / x......$ 1 to 7.15 rand = $ 1000 to x rand
cross multiply because this is a proportion
(1)(x) = (7.15)(1000)
x = 7150 <=== Sophia got 7150 rand

*PLEASE HELP WILL GIVE 60 POINTS I'M DESPERATE*
Zina [86]

Answer:

(0, 3)

Step-by-step explanation:

1. Find the slope:

\frac{y_{2} -y_{1} }{x_{2}-x_{1}  } =\frac{0-(-3)}{-4-(-8)}\\ \\=\frac{3}{4}

2. Calculate the y-intercept using a given point:

(-8, -3)

-3 = \frac{3}{4} (-8) + b

-3 = -6 + b

-3+6 = -6+6 + b

3 = b

3. Write in slope intercept form:

y= \frac{3}{4} x+3

Therefore, the y-intercept is 3.

The graph for this table is shown below.

hope this helps :)
